计算机视觉综合征（CVS）是一组与视觉相关的症状，这些症状是由于连续使用带有数字显示器的设备（如计算机，平板电脑和智能手机）而引起的。现在的学生可以很容易地在智能手机上找到在线资源和书籍，从而减少了纸质阅读材料的使用。这可能会导致一些眼部症状。在这项研究中，我们的目的是评估的患病率，并确定CVS的危险因素在沙特国王本阿卜杜勒阿齐兹大学健康科学（KSAUHS）在Jeddah.Materials和methodsThis是一个观察性的描述性横断面研究设计的学生。KSAUHS的医学、应用医学科学和科学与健康学院的学生被要求填写一份电子自我管理调查。调查工具包括人口统计信息，数字设备使用习惯，眼部症状的频率，和人体工程学的practices.ResultsThe样本量为334名学生，其中55%是男性的问题。使用最多的设备是移动的电话（78%），使用电子设备最常见的原因是娱乐（80%）。报告的眼部症状频率如下：头痛（68%），感觉视力受影响（近视或远视（65%））、眼痒（63%）、烧灼感（62%）、流泪过多（58%）、视力不清（52%）、发红（51%）、干燥（48.3%）、恐惧症（47%）、眼痛（44%）、异物感（40%）、过度眨眼（40%）、难以聚焦近物（31%）、物体周围光晕（28%）、复视（21%）和眼睑移动困难（9%）。最常用的人体工程学实践是根据周围的光线亮度调整显示器亮度（82%）。其余的人体工程学实践应用较少，如下：使用设备时休息（66%），坐着时屏幕与脸齐平（59%），坐着时屏幕顶部与眼睛齐平（43%），坐着时屏幕距离超过50厘米（32%），使用防眩光滤光片（16%）。报告的眼部症状数量在女学生中明显更多（使用Mann-Whitney U检验）（U= 11056.500，p= 0.002），戴眼镜的学生（U= 11026，0.002），以及在屏幕上观察眩光的学生（U= 8363，p= 0.043）.结论CVS症状在使用不同电子设备的健康科学专业学生中常见。CVS症状的发生率在女学生、观察屏幕眩光的人和戴眼镜的人中显着较高。然而，器械使用时间长与CVS症状增加无显著相关性。大多数学生通常不会应用人体工程学实践，这需要更多的努力来提高他们对正确使用设备的意识。
IntroductionComputer vision syndrome (CVS) is defined as a group of vision-related symptoms that result from the continuous use of devices with digital displays, such as computers, tablets, and smartphones. Students nowadays can find resources and books online on their smartphones easily, hence, reducing the use of paper-based reading materials. This might lead to a number of ocular symptoms. In this study, we aim to assess the prevalence and determine the risk factors of CVS among students at King Saud Bin Abdulaziz University for Health Sciences (KSAUHS) in Jeddah.Materials and methodsThis is an observational descriptive cross-sectional study design. Students of Colleges of Medicine, Applied Medical Sciences, and Science and Health Professions at KSAUHS were asked to fill an electronic self-administered survey. The survey instrument included questions on demographic information, digital devices using habits, frequency of eye symptoms, and ergonomic practices.ResultsThe sample size was 334 students, 55% of whom were males. The most used device was the mobile phone ( 78%), and the most common reason for using an electronic device was for entertainment (80%). The frequency of reported eye symptoms was as follows: headache ( 68%), feeling of an affected eyesight (short- or long-sightedness (65%)), eye itchiness (63%), burning sensation (62%), excessive tearing (58%), unclear vision (52%), redness (51%), dryness (48.3%), photophobia (47%), painful eye (44%), foreign body sensation ( 40%), excessive blinking (40%), difficulty in focusing on near objects (31%), halos around objects (28%), double vision (21%), and difficulty moving eyelids (9%). The most commonly applied ergonomic practice was adjusting display brightness based on the surrounding light brightness (82%). The rest of the ergonomic practices were less applied as follows: taking breaks while using the device (66%), sitting with the screen on face level (59%), sitting while the top of the screen on eye level (43%), sitting with the screen more than 50 cm away (32%), using antiglare filter (16%). The number of eye symptoms reported was significantly greater in female students (using Mann-Whitney U test) (U= 11056.500, p= 0.002), students who wear glasses (U= 11026, 0.002), and students who observe glare on their screens (U= 8363, p= 0.043).ConclusionCVS symptoms are commonly reported among health sciences students who use different electronic devices. The occurrence of CVS symptoms was significantly higher among female students, those who observe glare on screens, and those who wear eyeglasses. However, long duration of device use was not significantly associated with increased CVS symptoms. Ergonomic practices are not usually applied by most of the students, which necessitates more efforts to increase their awareness of the correct way of using devices.
